To summarize: - Booting the laptop in the dock, both the internal laptop display and the external DVI display connected, shows the beginning of the boot process on the internal display and then both displays go blank. - Booting the laptop in the dock, internal display in use and the external display powered *off*, shows the kernel boot process on the internal display but when GDM should show up the internal display goes blank. Nothing on the external display either (if I power it on). - Booting the laptop without the dock (and without the external display) works OK, I can see kernel boot process and GDM/X just OK. - Booting the laptop without the dock, and attaching it to the dock after X is running allows me to use (=enable) the external display once. But Gnome Monitor application shows the external display twice (as two devices).. -- Pasi _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
